IRONMAN 4X4 U-bolts are simply the best option for securing your leaf springs to your 4x4's axle!
Great quality high carbon coated U-bolts
Ordered with my leaf packs but never got these I bolts with my order
Be prepared to have to widen the holes on your mounting bracket, as these are wider than the stock u bolts. Easy to install and durable quality
What length are these U bolts? What is the dimensions? Are they OEM specks or for a lifted rear and??
This kit is made for medium load leaf springs on the 2005-2023 Toyota Tacoma. It does NOT work with 2WD models or with heavy load leaf springs. For heavy load leaf springs, use our Rear U-Bolt Kit for Heavy Load Leaf Spring (678UBK): https://www.ironman4x4.com/products/rear-u-bolt-kit-for-heavy-load-leaf-spring-for-toyota-tacoma-2005-2023-678ubktacoma
We don't publish the U-bolt length or dimensions for this kit.
